Hi everyone, I've been working on a project that essentially requires the extended disparity mode for the depth detection, but also needs to capture color footage from the main camera (using the gen2 API). I've seen the reference in the example explaining the limitations of certain depth modes [here](https://docs.luxonis.com/projects/api/en/latest/samples/03_depth_preview/), as well as [this post](https://discuss.luxonis.com/d/78-i-have-a-question-about-run-both-stereodepth-and-color-in-pipeline-gen2), but from what I can tell nothing I'm doing contradicts these known issues. I essentially am setting up the rgb camera according to the [tutorials](https://docs.luxonis.com/projects/api/en/latest/samples/01_rgb_preview/), and the same for the [depth pipeline](https://docs.luxonis.com/projects/api/en/latest/samples/03_depth_preview/). Extended disparity will work fine with just the depth pipeline setup, however as soon as I create simply the color camera pipeline object I am greeted with the following: ` in get_depth inDepth = q_depth.get() RuntimeError: Communication exception - possible device error/misconfiguration. Original message 'Couldn't read data from stream: 'depth' (X_LINK_ERROR)' ` If I disable the extendedDisparity then both pipelines will happily exist and run together. I'm mostly just wondering if I am misinterpreting the warnings in example 03 and they do actually mean you cannot run extended disparity in combination with rgb. If not, any kind of work arounds or advice would be much appreciated.

@"MattTav"#p946 Hi Matt and sorry for the late reply. Have you run [install_requrements.py](https://github.com/luxonis/depthai-python/blob/main/examples/install_requirements.py) first? We've made some changes recently. Could you try again? If you still have an issue, please let me know.

Issues running extendedDisparity with rgb cam

Hi everyone,

I've been working on a project that essentially requires the extended disparity mode for the depth detection, but also needs to capture color footage from the main camera (using the gen2 API).

I've seen the reference in the example explaining the limitations of certain depth modes here, as well as this post, but from what I can tell nothing I'm doing contradicts these known issues.

I essentially am setting up the rgb camera according to the tutorials, and the same for the depth pipeline. Extended disparity will work fine with just the depth pipeline setup, however as soon as I create simply the color camera pipeline object I am greeted with the following:

in get_depth inDepth = q_depth.get() RuntimeError: Communication exception - possible device error/misconfiguration. Original message 'Couldn't read data from stream: 'depth' (X_LINK_ERROR)'
If I disable the extendedDisparity then both pipelines will happily exist and run together.

I'm mostly just wondering if I am misinterpreting the warnings in example 03 and they do actually mean you cannot run extended disparity in combination with rgb. If not, any kind of work arounds or advice would be much appreciated.

Cheers - Matt

Hello @MattTav,
so this is a known issue (reported here), we have a PR that should fix this(PR here). Could you try to install the fix either by checking out to that branch and running ./examples/install_requirements.py or by running
python3 -m pip install depthai==2.1.0.0.dev0+df16f1724b2969896fd39c086978da1da816a1c0 --extra-index-url https://artifacts.luxonis.com/artifactory/luxonis-python-snapshot-local
Thanks, Erik

Thanks for the replies, I actually ended up asking on the discord and Alex put me on to the stereo-fixes branch which has been working perfectly for me!
